Note
: How the data is transferred depends on the measuring frequency set on the device. With the set
measuring frequency of 100 Hz, the data is transferred directly and continuously from the start of the
measurement. If the measured frequency is above 100 Hz, the measurement data is first cached in the
meter due to a limitation of the USB interface and then transferred at the end of the measurement.

Calibration
The calibration of the display devices and sensors is done in a certified laboratory using traceable
calibrated weights (up to 1000 N) or traceable calibrated reference-force gauges (1000 N).
It is recommended to carry out and certify recalibration annually.

Battery life and charging
In the compartment on the back side of the meter there are three environment friendly AA battery packs
that are fully charged before delivery. To charge the batteries, the USB power adapter supplied should be
used. Please work several times until the complete discharge of the batteries and charge them again only
after that. In case of lasting use, for example, in small tests, disconnect the charger at least once a week
during working hours and wait until the full discharge of the batteries. Please charge the device only after
that again. The normal working hours with a fully charged battery pack is about 10 hours. The necessary
charging time is approximately 3 - 4 hours. The current state of charge of the batteries is shown at any
time in the upper right corner of the display. If the batteries have reached their maximum service life and
no longer have their full power, so standard AA batteries or in case of emergency 1.5V AA batteries can
be used. Please note that the working time with standard batteries is limited. When connecting the
delivered charger you can see the state of charge by the moving battery icon in the upper right corner of
the display. Please note that the new batteries reach their full capacity only after a few charge / discharge
cycles. It is recommended to connect the handheld instrument to the charger after each use or daily.
Note: It makes sense to discharge the batteries after long use as much as possible and to charge them
fully again.

SD memory card
A memory card with a capacity of 2 GB is included in the delivery. On it, the meter stores accumulating
peak values and curve files. Alternatively, for data transmission via the USB cable, this card with the help
of a small pressure can be taken out of the slot located on the right side. With the help of a SD card
reader it can be read on any computer. SD memory cards up to 4GB are supported.
10 In- and outputs
10.1 Mini-USB interface
The USB-data cable is included in the delivery.
10.2 Output
The analog output is proportional to the measurement value. This has a max. value of ± 2 V DC,
according to the nominal range of the hand-held meter.
A possible calibration of the analog output at two measuring points is available optionally.
Note
: The zero adjustment on the display device is carried out in the unloaded condition of the load cell.
